[Representative's message]
We hope to manufacture articles that are not made by other companies, that are desired by many people, and that inspire our spirit of Monozukuri craftsmanship. Our goal is to be a modern group of artisans and an ideal factory, fastidious about inheriting the corporate DNA of Sony’s co-founder Masaru Ibuka. Each of the world’s SMEs has a key person who supports the enterprise with unique and excellent technology without slipping into self-complacency. We think we can manufacture globally second-to-none products by closely cooperating with these companies, just like weaving textiles. We are proud of the craftsmanship that achieves such unique products.
